Whoops! We were completely seduced by the swings and the back wooden room, and it did say it had "AC." Well, it had a small AC window unit in one room - nothing that could keep up with the humidity! Still, we had a ball. Saugatuck and South Haven were as fun as advertised, and we DID enjoy reading on those swings and having dinners over that table in the back room, so overall it was a success. If 3/4 of us didn't have allergies that went absolutely stark-raving bonkers, we would return. I'd also recommend it to anyone who didn't suffer from allergies. We never saw the owners, but they were responsive via email & text, and left clear instructions. They left a bit of firewood for us out back (which we had fun using), with the option to buy more bundles at $5/each, which I assume is cost. Completely reasonable. The bathroom was a tight fit, but the showerhead was lovely, and the kitchen had everything we went looking for (we cooked on site).
I had no problem with the clean mattress, but my partner complained about the lack of box springs. I've always tolerated a firmer mattress than he has. I did have trouble with the bedspread and pillows. Fortunately I brought allergy pillow covers, and there was a blanket at the foot of the bed that was less dusty/allergy-inducing.
I hope this helps you decide whether it's the place for you. Have fun!
